Speed Monitor OFTA (SOFTA)

Introduction

The Trusted piece of equipment. It provides the output field interface for one rotating machine group when used as part of a Trusted

Both normally open and normally closed volt free contacts are available on the field terminals. This allows the SOFTA to be used in energised to trip and de-energised to trip configurations. .

The two relay output channels are arranged as quad redundant, fault tolerant structures. Failure of any one relay or contact will not affect the load, or the ability to control the load.

Load current feedback to the T8442 Speed Monitor is provided for each switching path on each channel.

Speed Monitor Output Field Termination Assembly (SOFTA) is a DIN rail mounted

T8442 TMR Speed Monitor system.

Force guided contact safety relays are used. These allow the T8442 Speed Monitor to detect welded or stuck output contacts via the contact status and load current feedback from the SOFTA.

Each relay, fuse and current-sensor can be replaced in situ.

Features

• Two online tested, fault tolerant, volt free contact output channels

• Each output can be used as either a normally open or a normally closed contact.

• Fault tolerant quad redundant output relay structure.

• Load feedback monitoring.

• Contact status feedback.

• Force guided contact, safety relays.

• Standard DIN Rail mounting

• Each output rated

• Relays, fuses and current sensors can all be replaced in situ.
